Enviga(ration) tastes good

I don't love Enviga because it claims to burn calories...I workout to burn calories. However, I LOVE ENVIGA because when I have to pull an all-nighter it keeps me cranking. When there is a time I have to stay awake Enviga is my lifeline. It also has 5 calories and the berry flavor actually tastes good...unlike energy drinks. I can't live without it!
